Clinical management of pelvic relapses from gynecologic malignancies remains challenging.  Bulky pelvic relapses often lead to symptomatic cancer-related complications and poor clinical outcomes.  Options may be limited by prior surgical, chemotherapeutic, and radiation treatment.  Stereotactic body radiosurgery is a novel treatment modality which allows high radiation dose delivery in a non-coplanar fashion with sub-millimeter precision utilizing a linear accelerator mounted on a robotic arm.  This study details our clinical experience with stereotactic body radiosurgery for treatment of patients with pelvic relapses of gynecologic malignancies after prior pelvic radiation.
